WHEEL AND WHEEL-RIM.

SPECIFICATION forming part of Letters Patent No. 743,098, dated November3, 1903.

Application filed October 27, 1899. Serial No. 734,919. (No model.)

the accompanying drawings,-which form a part thereof.

My invention relates to the construction of wheels and wheel-rims,especially rims of sheet metal, having particularly in view theformation of rims for pulley-wheels, my prime object being to provide awheel-rim built up of segments which will'be at once strong,

true, and of easy and cheap construction.

The essential feature of my invention in the construction of the rimconsists inv forming a rim of sheet metal folded together intermediateof its edges to form an inwardlyextending two-ply flange and folded outwardly from the top edges of the twoply flange to form the face of thewheel. The edges of the folded plate are also preferably folded inwardto form strengthening ribs or flanges, and the plate havingthe T shapedcross-section described is curved in the plane of its central flange tothe desired curvature of the wheel-face. The central flange of thewheel-rim section constructed as above noted serves for the attachmentof the spokes of the wheel-center and also serves to stiffen and makepermanent the curvature of the face of the rim, the edge flanges alsoserving the purpose of stiffening and making permanent the curvature.

While my new rim can be used with hub and spoke constructions of Variouskinds, I have especially designed for use with the T- shapedrim-sections a cast-iron wheel-center the spokes of which are bifurcatedat the ends to permit the entrance between its separated end lugs of theinwardly-extending flange of the rim, which is secured to the spokes byrivets passing through the lugs and flange.

Reference being now had to the drawings, in which my invention isillustrated, Figure 1 is a sectional view of a split pulley having myimproved rim and cast-iron center, thesection being taken as on the line1 1 of Fig.

2; Fig. 2 is an edge view of the split pulley withthe edge cut away onthe line 2 2 of Fig. 1. Fig. 3 is an enlarged View of the under side ofthe joint or union formed between two abutted rim-sections. Fig. c is anedge view of the joint shown on the same scale as Fig. 3. Fig. 5 is anedge view taken on the section-line 5 5 of Fig. 3. Fig. 6 is aperspective view showing the folding of the end of the plate forming.the joint as represented in Figs. 3, 4, and 5. Fig. 7 is a perspectiveview showing a modified manner of folding the plate at its end. Fig. 8is a view of the inside of the joint formed by two abutted rim-sections,the joint here being of a modified and different character. Fig. 9 is anedge view of the modified joint shown as on the section-line 9 9 of Fig.8, and Fig. 10 is a view illustrating a convenient way of forming thejoint when the rim-sections are used in making up the face of a solidpulley.

A A indicate the hub-sections of the split pulley, said hub-sectionsbeing formed with outwardly-extending perforated lugs A and with radialspokes, (indicated at A A &c.)

A indicates enlargements at the end of the spokes, formed with centralslots, as indicated at a to receive the central flange of the rim.

' B B indicate bolts, by means of which the hub-sections are securedtogether.

0 C indicate rivets, by'which the lugs of the enlarged spoke ends Aseparated by the slots a, are firmly secured to the web of the rim.

D D indicate rim-sections constructed in accordance with my invention.They are formed of sheet-metal strips folded together intermediate oftheir edges, so as to form inwardlyextending circumferential two-plyfolds, (indicated at D D.)

D D are outward folds of the metal extending from the top edges of theflange-folds 1 D and forming the face of the pulley or wheel.

D D indicate inwardly-folded edges of the plates, forminginwardly-extending flanges, as shown. As clearly shown in Figs. 1, 2,and

ICC

/tlie plane of the flange D D and to the curvature of the desiredwheel-rim, the ends of the rim-sections being abutted together, and itis preferable that the abutted edges should be firmly locked in place,as it will be understood that the pulley is more likely to becomedistorted at the joint than at other points. In Figs. 3, 4, 5, and 6 Ihave illustrated a convenient and satisfactory way of forming thejointat the abutted ends of the rim-sections, the ends of the rim being bentinward at a right angle to the face of the rim, forming flanges, as

indicated at D D", which of course are practically in planes radial tothe center of the pulley.

To make this end flange, it is of course necessary that the centralrim-flange D should be out. Preferably I out it away at an angle ofninety degrees, so that the bevel edges, as indicated at D and (1 willabut together, (see Fig.

6,) the portion of the central web attached to the folds D Dbeingindicated at d. The ends of the rim-sections being bent to thepositions shown in Fig. 6 are then firmly secured together byangle-irons, as indicated at E E E the portion E lying against the endfolds D, the portions E lying against the central flanges made up of theportions D and d, and

the portions E abutting against the edge folds D Rivets are convenientlyemployed to secure the portions E and E of the angle-iron to the flangesof the rim, and bolts are employed, as best shown in Fig. 3, to securethe plates E and flanges D 'together and to secure the abutted flangesin position. I have also braced the inwardly-turned folds D in positionby separating the web portions 01 from the web portions D by means of astraight out, as indicated at D d and then lapping the portion (1 on theportion D, as indicated in Fig. 7, employing rivets to secure the lappedportions together.

In Figs. 8 and 9 I have shown an abutted joint in which the rimsectionsare not turned in at the ends, but are abutted against each other andsecured together by angle-irons E E the portions E of the irons beingriveted to the rim and the portions E riveted or bolted together. Theabutted joint between the rim portions is indicated at D D".

- Where the pulley is a solid and not a split one the joint may be madeas shown in Fig. 10, in which I have partly broken away one of the lugsof the head A on one side of the groove a formed in it. In thisconstruction the two rim-sections D D form an abutted joint, as in Figs.'8 and 9, the joint being braced and the parts alined by bringing one ofthe spokes of the pulley into alinement with it and riveting the ends ofboth sections of the rim to the same spoke of the pulley.

I am aware that sheet-metal wheel-rims have heretofore been made up ofseparate flanged segments, two or more such segments being abuttedtogether to form the full breadth of the rim and intermediatecircumferential two-ply flanges; but in all such constructions the pliesof the intermediate flanges are merely in contact and only held togetherby separate fastening device. My

. rim is distinguished from such prior constructions by the union of theplies of the flanges throughout their inner edge, whereby the structuralstrength of the flange is greatly increased and the strength of the rimas a whole and also the correct alinement of the parts on each side ofthe flange is greatly promoted.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is r 1. A wheel-rim section consisting of aplate of sheet metal folded together at a point intermediate of itsedges to form an inwardlyextending two-ply flange suitable forattachment to the spokes of the wheel and folded outward from the topedges of the flange-folds to form the face of the wheel, said foldedsection being curved circum ferentially in a plane parallel to theflange.

2. A wheel-rim section consisting of a plate of sheet metal foldedtogether at a point intermediate of its edges to form aninwardlyextending two-ply flange suitable for attachment to the spokesof the-wheel, said plate being folded outward from the top edges of theflange-folds to form the face of the wheel and again folded inward atits edges to form strengthening-ribs, said folded section being curvedcircumferentially in a plane parallel to the flange.

3. A wheel-rim formed of plates of sheet metal folded togetherintermediate of their edges to form inwardly-extending two-ply flangessuitable for attachment to the spokes of the wheel and folded outwardlyfrom the top edges of said flanges to form the face of the wheel, theends of said plates being bent in at right angles to form abutting facesand secured together in forming the complete rim.

4. Acast-metal wheel-center having formed integral with it, radialspokes slotted at their ends, in combination with a rim of T-shapedsection formed by folding sheet metal together to form a two-ply web andoutwardly from the top of the web-flange to form the face of the wheel,said rim-section having its two-ply web fitted into slots of the spokeends and secured thereto.
